Elin:Symbiosis

Symbiosis allows a pet to "ride" you. (Think Venom from Spider-man). This causes you to both occupy the same tile. This causes a penalty to your accuracy and speed, however these penalties can be at least partially mitigated by leveling the Symbiosis skill. The main benefit to Symbiosis is that enemies tend to target the player over their symbiote. This means that an ally with low defenses can be protected.
